Chemoselective alkoxycarbonylation reagent having trifluoromethylsulfonyl-4-trifluoromethylanilide as a leaving group†
Abstract
N-Benzyloxy- and N-tert-butoxycarbonyltrifluoromethylsulfonyl-4-trifluoromethylanilides were prepared and were found to be chemoselective and shelf-storable alkoxycarbonylation reagents.
